A third photo (check it out in the video above) shows Silas in Timberlake's lap. "We're watching the PGA championship," Timberlake said, joking that his mini-me is "great putter" and they are working on his swing.

Since Silas' birth in April, the new parents have shared just two of photos of him on social media. The first picture came when he was just a few weeks old and wore a Memphis Grizzlies shirt. The second snapshot came on Father's Day, when he was in Timberlake's arms and wore a onesie embroidered with the words "I Love Dad."

Later on, Timberlake pimped his 901 Tequila brand and showed Fallon how to make the perfect cocktail. And, of course, the funny pair also performed "The History of Rap 6":
